Detailed Description

This Dorman blower motor resistor kit is made for HVAC systems that have lost blower speed control due to heat damage or corrosion at the original resistor connector. The included harness pigtail supports repair of the electrical connection while the resistor restores blower motor speed selection in the cabin climate control system. For Toyota Previa owners, Dorman 973-151 provides a practical replacement path when the original resistor assembly has failed from age or electrical wear.

Compatible With 1991-1997 Toyota Previa, N/A. This part number, 973-151, is also referenced in service and catalog listings for the same vehicle application. If you are searching for a Toyota Previa blower motor resistor kit, Toyota Previa HVAC resistor replacement, or Dorman 973-151 for 1991-1997 Toyota Previa, this part matches that repair need.

What It Helps Fix

• Blower motor speeds that stop working or only operate on certain settings
• Heat-damaged resistor connectors at the HVAC housing
• Corroded or worn electrical terminals in the blower resistor circuit
• Intermittent cabin fan operation caused by poor electrical contact
• HVAC fan control issues in a 1991-1997 Toyota Previa

Installation Notes and Tips

Inspect the resistor connector, terminals, and surrounding HVAC housing before installation. Replace any damaged wiring at the same time so the new resistor has a clean electrical connection. Confirm the vehicle uses the listed blade-terminal, 4-wire configuration before ordering and follow the service manual for access and mounting procedures.

Quality Assurance

Dorman supplies replacement electrical and HVAC service parts for vehicle repair applications. This kit is built to replace an overheated or corroded original equipment resistor on the listed Toyota Previa models.
